Description

Liked the idea of a filament straightener.

Modified to suit bearings (696ZZ) and machine screws (M5 button cap) to hand ( these are a sloppy fit in the bearings inner diameter before some insulation tape packing; ideally you would have M6 button caps in the 6mm internal diameter bearings :o) )

Original parts are included as they are imported into the openSCAD files for the modifications.

1 base (with or without filament guide)
